Abstract:

In mobile access networks, different types of Internet of Things (IoT) devices (e.g., sensor nodes and smartphones) will generate vast traffic demands, thus dramatically increasing the traffic loads of their connected access nodes, especially in the 5G era. Mobile edge computing enables data collected by IoT devices to be stored in and processed by local fog nodes as well as allows IoT users to access IoT applications via these nodes at the same time. In this case, the communications latency critically affects the response time of IoT user requests. Owing to the dynamic distribution of IoT users, drone base station (DBS), which can be flexibly deployed over hotspot areas, can potentially improve the wireless latency of IoT users by mitigating the heavy traffic loads of macro BSs. Drone-based communications poses two major challenges: 1) DBS should be deployed in suitable areas with heavy traffic demands to serve more users; 2) traffic loads in the network should be allocated among macro BSs and DBSs to avoid instigating traffic congestions. Therefore, we propose a TrAffic Load balancing (TALL) scheme in such drone-assisted fog network to minimize the wireless latency of IoT users. In the scheme, we divide the problem into two sub-problems and design two algorithms to optimize the DBS placement and user association, respectively. Extensive simulations have been set up to validate the performance of TALL.

Characterization and Modeling of GaN HEMT Trapping Effects for Microwave Circuit Design
Sep 2 @ 11:00 – 12:00

 

IEEE Ottawa Section: MTT-S / AP-S Chapter presents:

Title: Characterization and Modeling of GaN HEMT Trapping Effects for Microwave Circuit Design

Date: September 2nd, 2020

Time: 11 AM (ET)

Register at: https://events.vtools.ieee.org/m/238482

This talk will review some recent advancements achieved on the characterization and modelling of the trapping effects felt in GaN HEMT transistors, and their impact on microwave circuit design. Because of their nowadays importance, a particular attention will be payed to applications on high power amplifiers for mobile wireless infrastructure and pulsed radar applications.

For that, the talk will start by recollecting the most common model formulations adopted for the various levels of RF engineering, from the device level (physics) to the transistor (circuit) and amplifier (system) level. Starting by the Shockley-Read-Hall capture and emission processes we will be able to understand one of the fundamental signatures of trapping effects, the significantly different charge and discharging time constants, and its impact on power amplifier nonlinear distortion behavior. Then, some widely adopted approaches of the channel current transients’ characterization are addressed and the talk concludes by presenting some illustrative cases of application to RF high power amplifiers.

IEEEXtreme is a worldwide Annual Hackathon, in which teams of IEEE student members participate against each other in a span of 24 hours to solve a set of programming problems. This year IEEEXtreme 14.0 is being held on October 24th. Ragunath Anbarasu, the web master and an active volunteer of IEEE WIE Ottawa has been selected as the Ambassador and Section Lead for the Ottawa region. In this session, he will walk through the IEEEXtreme competition and WIE HACK613, a mock hackathon IEEE WIE Ottawa is organizing as a practice for IEEEXtreme. Register Now! And learn more about the event!

Bio: Ragunath Anbarasu is currently doing his Masters in Electrical and Computer Engineering with Specialization in Data Science at Carleton University. He as been the Web Master of IEEE WIE Ottawa for almost a year and is extremely active in volunteering activities related to IEEE. He has been coordinating with the organizers in hosting this years IEEEXtreme Programming Competition in their respective student branches and supporting Non-IEEE Student Branch Members to get exposure to the Hackathon. He will be extending his help to students looking for support and guidance with information related to IEEEXtreme and connect them to a professional member.
